performance: Add explicit casts for some double → other numeric type conversions

Browse Source 
If we enable `-Wfloat-conversion`, these warn about a possible loss of
precision due to an implicit conversion from `double` to some other
numeric type.

The warning is correct: there is a possible loss of precision here. In
these instances, we don’t care, as the floating point arithmetic is
being done to do some imprecise scaling or imprecise timing. A loss of
precision is not a problem.

So, add an explicit cast to squash the warning.
